How to find general formula for partial sums?
Shtirlitz [24]

<span>A Partial Sum is a sum of sart of a sequence, where a sequence is a set of things (usually numbers) that are in order.</span>

Partial Sums are often written using Σ (called Sigma) to mean "add them all up":

<span>When you should calculate the kth partial sum of an arithmetic sequence, you need to add the first k terms. If k is large, than you will need a long time to calculate the sum. Fortunately, you can use a general formula instead of plugging in each of the values for n. </span>

The first thing you should do is to find the first term of the sequence.

<span>Then you should find the kth term of the sequence.</span>

<span>Then you should use the formula for the kth partial sum of an arithmetic sequence to find the sum.</span>

Express each rate as a unit rate. 720 miles traveled on 60 gallons of gasoline=
Brut [27]
720 miles traveled on 60 gallons of gasoline.
Express this on its Unit Rate.
To get the answer, we need to divide 720 miles by 60 gallons of gasoline
=> 720 / 60 = 12 miles /gallons
Thus, in every 1 gallon of gasoline, you can travel 12 miles.
So, the expression would be like this:
720 miles / 60 gallons = 12 miles / gallon
Let’s check our answer
=> 12 miles x 60 gallons = 720 miles.
Thus, we got the correct answer.

What is the slope of the line that goes through the points (4,-1) and (3,8)?
7nadin3 [17]

Answer:

The slope of the line is -9

Step-by-step explanation:

Given points are (4,-1)\ and\ (3,8).

The slope is change in y-coordinate over the change in x-coordinate

 m=\frac{y_2-y_1}{x_2-x_1}

And, we have

(x_1,y_1)=(4,-1)\\(x_2,y_2)=(3,8)

Plug the formula of the slope we get,

m=\frac{8-(-1)}{3-4}\\\\m=\frac{8+1}{3-4}\\\\m=\frac{9}{-1}\\\\m=-9

So, the slope of line passing through (4,-1)\ and\ (3,8) is m=-9
